What are Interactive Maps and how do I use them?
Interactive Maps is an online analysis tool that allows for visual exploration of geographic data using a U.S. map and drop-down menus. Color-coding enables quick visual identification of a state by category (e.g. percent). Interactive Maps are available on mobile devices as well as desktop computers and can be easily printed.
Currently, maps allow for state-level geographic analysis of the Treatment Episode Data Set - Admissions (TEDS-A) series beginning with the year 2005. Maps for additional years of TEDS-A, other studies, and other geographic levels are planned for future release.
To begin using the maps, follow these steps:
- Select the year of data you wish to analyze.
- Select the substance of interest. Substances are those reported at admission and may have been reported as the primary, secondary, or tertiary substance of abuse.
- Click the "go" button.
- Move the cursor over a state to view the count and percentage of the substance at the time of treatment admission.
Several resources are available for assistance while using the maps:
- A color-coded key beneath the map defines the varying degrees of response across the geographic level of analysis.
- Zoom buttons located at the bottom-left of the map allow for zooming in on a geographic area. This is useful when trying to select one of the smaller states or the District of Columbia.
- A map citation is provided for proper documentation of the map.
- A hyperlink beneath the citation provides access to a tabular display of the data.
- The Related Resources section gives quick access to the selected study and series home pages.
